Well-prepared and informative course. The instructor is explaining concepts briefly and very clearly. He is a legend in teaching. 4 stars because there are a lot of mistakes in the quizzes and final assessment. I wish I will not have like these mistakes in the upcoming courses in this specialization.

course material is not bad. Few errors here and there, but they are easy to spot. The course assignments and quizes are dire. Several mistakes, including the end assignment, which means unless I bite the bullet and put the WRONG answer in, I'll never get 100%. For those interested: Question 8 is abigious - What is the right answer? Question 19 is completely wrong (It IS diagram 2) You ask for complete SQL statements and then key words, and then back to SQL statements, so if someone puts in the full SQL statement, the very basic assignment marking system goes "Oh I can't see a single word of 'Values', it must be wrong". Oh and you have member number in the question and player number in the answer, also who stores telephone numbers as ints?! Please for the love of gods, improve this. I'd be happy to help!

There are so many typos and inconsistencies in the reading sections of this course. Some typos are ok, for example, some mispelling words. Even the cases when the code sometime use capital letters and lower case letters inconsistently. It is confusing but this is still ok, you just need to be aware of it. The problem comes with week 4. When talking about normalization process, the ERD is not consistent with the actual implementation and there are so many errors in the normalization processes, this can be misleading for beginners. And I also think the explanation of first normal form in this course is wrong. There should be more refinements for this course. If those problems are solved, I think it is worth taking.

I am really inspired to learn a difficult subject in the easy way due to relax, comprehensive and informative tutorials , lectures

Honestly, I'm disappointed. Meta should be too, this course is taught well but the amount of typos in the material and issues with the quizzes is frankly unacceptable. I wouldn't want my brand associated with something that seems as carelessly put together as this. The information presented is good, some of it is very high quality. But courses with careless typos and issues with their quiz questions just frustrate learners and discourage them from continuing. Step it up, Meta...

Well detailed course, I thought this topic was going to be hard to learn. But the teacher explained it well. Anyway, I enjoy this course, because I learned a lot from it. Thank you Coursera and Meta.

With regards to Coursera, I'm super disappointed with their customer service, because there seems to be none. With regards to this course, considering it has been put out by the makers of Facebook, the introduction is the only up-to-date part, as the content is sorely lacking. Assessments often ask for answers that have yet to be taught, and their lab interface should be easily available outside of the required lab work so people can practice. The programming for the week 5 assessment is horribly flawed - it won't matter how you answer, or how many times you go through the assessment, you will get marked wrong, which is where customer service, or a chat box, or anything responsive would come in handy - and as such it does nothing but eat time, energy, and burn hope. If you are looking to spend money or use this certification for a job, then don't choose this course on this platform.

Great lessons. The final quiz had some questions that showed that you answered the question incorrectly even though the exact same SQL statements executed perfectly in MySQL.

Thank you so much for the opportunity to learn Introduction to Database learn New things with crisp and clearly Taught Menter and Meta and Coursera thanks for help me..

This course is so much better than Introduction to Data Analytics. The guidance is clear and the instructor speaks at a very good pace.

Easy for a beginner and even for a refresher. The concepts are well explained and follow up exercises enhance understanding.

Videos use SQL via "PHPMYADMIN", there is NO WAY to follow if we "Students" are using "LAB SQL". Also, having more hands on in UPDATING, DELETING, and MODIFYING tables would be GREAT!!!!

Final test was hard....SQL Query works on LAB but test did NOT recognized correct answer! SO AGGRAVATING!!!!

Course was good, however quizzes and graded assessments needs work. From my perspective whether some of the question texts are ambigious/not clear, or the grading engine not functioning properly.

Learning materials are great, but the final test is crap, sorry. In some places it is not clear at all what does the test want me to write in the answer box. I type in the right code, because I've just tested it in the mysql command line, but the test still fails. What the hell does "evaluate" mean? What code do you want me to write, what commands? Is it select or something else? Please use more concise wording.

A pretty shallow dip into the world of database systems in my opinion. I think I learned the most from reading my textbook and the additional readings at the end of each module.

This course was outstanding. The instructor explained all the concepts well, and he was very professional. Besides, despite being an introduction, he covered plenty of topics, and his examples were clear. Thanks, Meta and Coursera, for this excellent course.

This course is directed towards learning the basics of DBMS/RDBMS. The foreign key and Normalization concepts are explained clearly. One can take this as a refresher course on RDBMS concepts.

Muito bom e com ótimos labs

Coming from a SQL Server background, it was interesting to see and learn a few things about mySQL. Data Normalization reinforced what I had learnt many years ago. The labs worked well, although, for some segments, there wasn't an option to launch the lab (strange). The questions were a little poorly designed; for instance, the names added in a particular table differ from question to question. I also found that two of my correct answers were marked incorrectly. Overall, I rate this course a 4/5.

There are some technical issues to be solved, but nothing that compromises all the knowledge acquired. Great course!

A lot of errors within the material and the final test. I would've thought that this would have been proofread, QC'd and had someone run through the course before publishing it. Very disappointing and unprofessional of Meta and Coursera!

The Course delivery is great but there are a lot of errors in the course materials.

Lots of typos. Lots of unreadable pictures that don't match the description. It feels like no one even looked at the course before posting it on Coursera.

Course worked reasonably well and I learned a lot about databases and MySQL. As ALWAYS, there are a few minor issues with quizzes and labs being a bit wonky when it comes to grading. IMHO, all questions involving MySQL Syntax should adhere to what MySQL accepts. For example, if MySQL is case agnostic, then all labs and quizzes should be too. Same applies for spacing around operators and after keywords, etc. I think there should be more opportunities for working with operators (especially "modulus" - almost new to me). Lastly, you might suggest in the labs that students make copies of their syntax in a text editor so that they can "rebuild" databases & tables without having to retype everything multiple times. (Get it right the first time and reuse the code). Didn't bother with redoing the final quiz - I passed, plus there was no guarantee I'd see the same test again - in fact, I hope you guys are using a series of tests to keep everyone on their respective toes. Lastly, it really wouldn't hurt to have someone close out some of the discussion items after they have been resolved. An occasional "thank-you" to the original posters, after a proactive response, would probably eliminate most of the people bailing out of this specialization. Just my 0.02 - YMMV. V/r, BB

This is a highly useful course for beginners who know nothing about databases and SQL. However, as someone familiar with databases and SQL, I was able to complete this course quickly, skimming through or entirely skipping sections that covered the basics of SQL itself. Despite this, I found the course valuable for two main reasons. First, it provided an opportunity to review CRUD queries. For professionals like me who rarely perform direct CRUD operations on databases and primarily use DML or DQL, revisiting CRUD queries was beneficial. Second, the section on normalization was particularly helpful. Normalization has always been a confusing topic for me, but the clear diagram explanations and repetitive checks through assignments helped solidify my understanding. Additionally, the course is well-structured to ensure beginners can fully grasp conceptual topics, such as database schema design, at a foundational level. That said, it’s important to note that this course alone should not lead to the misconception that a database engineer’s job is limited to this level. The content is very basic, and real-world work will require experience with more complex queries and a deeper understanding of database operations.
